30 Οκτ 2023 · The suprascapular nerve is the lateral branch of the superior trunk of the brachial plexus. It receives nerve fibers that originate in the nerve roots C5 and C6 (and sometimes C4). The suprascapular nerve is a mixed nerve, meaning that it provides both sensory and motor supply for the suprascapular region. The main function of this nerve is to ...
19 Σεπ 2023 · Course. The suprascapular nerve originates from the superior trunk of the brachial plexus in the neck, containing fibres from roots C5 and C6. Fig 1. Course of the suprascapular nerve. It first passes laterally across the posterior triangle of the neck. The nerve then travels underneath the trapezius muscle, before traversing the suprascapular ...
The suprascapular nerve is a peripheral nerve of the shoulder and arm. It arises from the upper portion of the brachial plexus, which is a network of nerves that stretches across your neck down to your armpit. The suprascapular nerve’s roots emerge from the fifth and sixth cervical vertebrae (C5 and C6) in your neck.
23 Σεπ 2023 · Structure. Type: The suprascapular nerve is mostly a motor nerve, providing innervation to two key muscles of the shoulder: the supraspinatus and infraspinatus. It also carries some sensory fibers from the shoulder joint. Origins: The nerve usually originates from the superior trunk of the brachial plexus, which is formed from the C5 and C6 ...
Anatomical terms of neuroanatomy. [edit on Wikidata] The suprascapular nerve is a mixed (sensory and motor) nerve that branches from the upper trunk of the brachial plexus. It is derived from the ventral rami of cervical nerves C5-C6. It provides motor innervation to the supraspinatus muscle, and the infraspinatus muscle.
The Suprascapular (n. suprascapularis) arises from the trunk formed by the union of the fifth and sixth cervical nerves. It runs lateralward beneath the Trapezius and the Omohyoideus, and enters the supraspinatous fossa through the suprascapular notch, below, the superior transverse scapular ligament; it then passes beneath the Supraspinatus, and curves around the lateral border of the spine ...
3 Οκτ 2022 · Suprascapular nerve injury has recently gained popularity as a leading cause of shoulder pain and weakness. The course of the nerve through narrow osseoligamentous structures renders it susceptible to compressional and traction injuries at the suprascapular and spinoglenoid notches. Knowledge of the anatomy of the nerve is necessary to diagnose and provide the best clinical outcomes in cases ...
